Interesting post from Jens Weller on the new concurrency features in C++ 11 and C++ 14. He gives examples of code written using standard library async, futures and “.then()” with lamdbas, compared to the simplicity of expressing the same functionality with the proposed resumable functions (that is, resumable and await as language keywords).

Whilst resumable and await won’t be part of the language until at least C++17, Weller points out that Microsoft may put implementations into Visual Studio well before that. Here’s the paper, N3722.
